Elevator door panel type smoke blocking structure

The present invention relates to a fire-blocking structure, in particular to a smoke-blocking structure that can be guided by a door panel to prevent smoke from escaping into the elevator section.

According to statistics and investigations on the casualties of firefighters after a fire accident, most of the people who could not immediately escape from the fire were suffering from breathing caused by the smoke caused by the fire, and eventually they were swallowed by the evil fire. To this end, the relevant regulatory authorities require the construction contractor to launch the construction project. At the same time as the construction drawing of the building, it is necessary to propose a complete fire protection design for the fire protection equipment. After completion, the fire safety inspection certificate should also be issued to the building. The use of licenses, known as fire-fighting equipment such as thermal detection alarm systems, fire-fighting systems, broadcasting systems, fire zones and escape equipment, etc., and the fire zones described therein are devices or structures that use fire or smoke to construct buildings. The object room is divided into several area spaces to prevent fire, smoke, heat radiation and heat convection from spreading to other safe areas during the fire, and to achieve the function of maintaining the safety of personnel in other fire zone; however, due to the current high buildings The higher the building is, the higher the height of the building may be. Some people may want to use the elevator to escape because the floor is too high, or just when someone is trapped in the elevator when the fire occurs, it is crucial whether the elevator section has smoke blocking function. important.

To this end, there is a related manufacturer that provides a smoke-blocking structure for this problem, as in the prior art of the Republic of China No. M427162, which discloses a fireproof smoke curtain, which contains a roll. a receiving mechanism, a fireproof cover and two second adsorption units, the retracting mechanism has a reel and a driving device for driving the reel, and a first adsorption unit is disposed on each side of the fireproof smoke curtain, the fireproof curtain The upper end is connected to the retracting mechanism and is suspended below the retracting mechanism, and each of the second adsorption units is respectively disposed at a position corresponding to the first adsorption unit for the first adsorption unit of the fireproof curtain Adsorbing to each other to isolate the flame, high temperature heat radiation and smoke when the fire occurs. However, the second adsorption unit is exposed on both sides of the passage, the inlet and outlet, or the elevator opening, etc., in addition to reducing the overall aesthetics of the building, the first adsorption unit is provided with the flexible element for a long time with the fireproof smoke curtain roll. In the retracting mechanism, it is easy to deform due to long-term maintenance of a single state, so that the first adsorption unit that flexes and deforms cannot generate flat adsorption with the second adsorption unit when a fire occurs. A gap is created so that the smoke can still spread from the slit to other locations. In addition, one of the first adsorption unit and the second adsorption unit needs to be a magnet, and the strength of the magnet suction determines the degree of the smoke blocking effect. If the setting is excessive, the installation cost is increased. If the suction is too weak, it will not produce a better smoke blocking effect, which does not conform to the original design intention. Moreover, it can be known from the above prior art that the retracting mechanism must be powered by the driving device to achieve the function of driving the reel to be lowered; that is, the driving device must additionally add other detecting devices such as detecting smoke or sensing temperature. In order to be turned on when a fire occurs, or when a fire occurs, another driver may be sent to start the driving device; if the fire occurs, the detecting device cannot turn on the power of the driving device, or the personnel may not have time to go. When the driving device is activated, the reel of the retracting mechanism cannot be lowered or cannot be immediately released. At this time, the smoke may have spread to the elevator section and enter the elevator, and the person trapped in the elevator may be exposed to the smoke. He died of hypoxia. Therefore, how to create an effective way to isolate the elevator section without using extra power or manpower in the elevator section to prevent the fire from spreading to the fire zone during the fire zone is a top priority for the relevant industry.
